This repository has some files related to this tutorial on creating a revolutions per minute (RPM) sensor using an Arduino board. You can find the code used in rpm_sensor.ino, a circuit diagram in ...

This project aims to create a device which can measure and display the operating RPM and AFR of a small combustion engine. A Hall effect sensor is used to sense the magnet in the engine's flywheel ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...
